Boneham P5628MK Press Fit Headless Drill Bushing

Product Description

The BONEHAM P5628MK is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. It carries an inside diameter of 41/64 inches, a body outside diameter of 7/8 inches, and an overall length of 1-3/4 inches. Manufactured from steel, this bushing is pressed directly into a drill jig plate without a head flange, providing a flush, low-profile installation. Inside diameter tolerance is held to a tight range of +0.0001 to +0.0005 inches, ensuring consistent tool guidance and hole location accuracy. This part is suited for metalworking, machining, and fabrication environments where repeatable drill positioning is required.

This bushing fits standard drill jig plate applications in manufacturing, toolroom, and production machining settings. The headless press fit design is chosen when a flush surface is needed on the jig plate or when head clearance is a constraint. It installs permanently into the liner or jig body and is not intended to be renewable or interchangeable during a production run. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in standard drill jig plates and fixture bodies requiring a 7/8-inch outside diameter press fit seat and a 41/64-inch bore.

Installation Notes

Installation is performed by tool and die makers or machinist professionals using an arbor press to seat the bushing into a properly sized jig plate bore. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing. Do not use impact tools to drive the bushing, as this can damage the bore or distort the bushing. Remove all chips and debris from the jig bore before installation.
